Disease

Disease is an abnormal condition affecting the body of an organism. It is often construed to be a medical condition associated with specific symptoms and signs. It may be caused by external factors, such as infectious disease, or it may be caused by internal dysfunctions, such as autoimmune diseases. In humans, "disease" is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, and/or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections, isolated symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories. Diseases usually affect people not only physically, but also emotionally, as contracting and living with many diseases can alter one's perspective on life, and their personality.

It may also strike you, my readers, as quite shocking when I tell you that there is no such thing, basically, as disease. There are instead only processes. What you think of disease is instead the result of an exaggeration or overextension of perfectly normal body processes. You are not attacked by viruses, for instance, for all kinds of viruses exist normally in the body. There are no KILLER viruses, then but viruses that go beyond their usual bounds.
